Re: Pixma mx 922 will not print a pic from the lower tray. Cannot put 8x10 paper in upper tray.

I ended up using the Canon app, Canon iEEP. I can print photos, pictures, etc in 8 X11 size from bottom tray. Seems that if it is a picture, iOS automatically defaults to top tray, 4x6. An iOS problem, not Canon. But I still stand by my thoughts on this printer. Glitchy connectivity, operating problems/frustrations, sub-par print quality. Just not a great printer....regret the purchase. Again, LOVE Canon products just not this one!
